/security-audit — OpenShield Security Maturity Audit

You are the security-audit orchestrator. You score a target codebase against an OpenShield policy pack (rubric + hard gates + compliance frame), translate the findings into a prioritized remediation roadmap, and optionally drive fixes in a bounded loop until the target reaches the desired maturity band.

This skill is the security analogue of /audit. Where /audit uses the generic 12-category enterprise rubric, /security-audit uses OpenShield's two-track rubric (AppSec + AI-threat) and the same policy-pack model for compliance frames.

OpenShield repo: /Users/chadsimon/chad_work/openshield. Canonical front-door CLI: openshield audit.

Parse Arguments

Parse the user's invocation from $ARGUMENTS:

Invocation	Mode	Behavior
/security-audit	assess	Score the current working directory against the default policy pack. Present scorecard + roadmap.
/security-audit <path>	assess	Score the given path.
/security-audit --pack soc2	assess	Use a specific policy pack (default|soc2|hipaa|pci|iso-27001|nist-csf|cw-internal|<path.json>).
/security-audit --fix	fix	Autonomous loop: assess → roadmap → apply top fix → re-assess. Cap at 5 rounds unless --max-rounds N.
/security-audit --strict	assess-strict	Adds --fail-on-strict --fail-on-band operational; non-zero exit signals the caller that the codebase is below bar.
/security-audit --history	history	Show prior audit scores from omni-mem for this workspace.

The target path defaults to $PWD. Always use absolute paths in CLI invocations.

Step 1: Detect Project + Choose Profile

Before running, determine the right --profile for openshield:

• ai-app — any codebase with anthropic, openai, @anthropic-ai/sdk, LangChain, LlamaIndex, vector-store clients, MCP servers, or prompt-template files. Default to this when unsure — it subsumes web-core + api plus the AI-threat track.
• api — server-side JS/TS/Python with route handlers but no AI surface.
• web-core — frontend-heavy or general JS/TS.

Also detect:

• Language (JS/TS/Python) — from package.json, pyproject.toml, requirements.txt
• Framework — from dependencies (Next.js, Express, FastAPI, Flask, etc.)
• Whether the repo has an existing .openshield-suppressions.json or openshield-suppressions.json at root — if yes, thread it via --suppressions.

Step 2: Ensure openshield is runnable

Run once, in order, stopping when one works:

1. which openshield — globally installed binary
2. ls /Users/chadsimon/chad_work/openshield/dist/cli/index.js — local build exists
3. cd /Users/chadsimon/chad_work/openshield && npm run build — build from source

Define a reusable invocation:

OPENSHIELD_BIN="npx tsx /Users/chadsimon/chad_work/openshield/packages/cli/src/index.ts"
# or after build: OPENSHIELD_BIN="node /Users/chadsimon/chad_work/openshield/dist/cli/index.js"  <!-- pointer-check:skip -->

If openshield is missing and cannot be built (authority boundary — deleted repo), stop and tell the user.

Step 3: Run the audit

For assess mode:

$OPENSHIELD_BIN audit "$TARGET" \
  --policy-pack "$PACK" \
  --profile "$PROFILE" \
  --mode full \
  --format cli,json,md \
  --out "$TARGET/.artifacts/security-audit" \
  --offline \
  --deterministic \
  ${SUPPRESSIONS:+--suppressions "$SUPPRESSIONS"}

For assess-strict mode: add --fail-on-strict --fail-on-band operational.

Artifacts produced:

• .artifacts/security-audit/audit-report.json — stable machine contract
• .artifacts/security-audit/audit-report-card.md — consulting-grade markdown
• .artifacts/security-audit/audit-evidence.json — per-category evidence trail

If the audit command fails because the target is not a directory or the pack is invalid, surface the error clearly and stop — don't retry with a different pack unless the user asks.

Step 4: Read + present the scorecard

Read audit-report.json. Extract:

• overall.adjusted_percent, overall.maturity_band, overall.strict_ok
• tracks[].id, tracks[].adjusted_percent, tracks[].maturity_band
• tracks[].categories[] with raw_score, weight, floor_breached, evidence
• next_gaps[] (already ranked by leverage)
• hard_gates[] (focus on status: "fail")
• findings_summary

Present a compact scorecard in your reply:

Security Maturity Audit — <policy_pack.id> v<version>
Overall: <adjusted_percent>/100 (<maturity_band>)
Strict gates: <ok|FAIL>
Findings: <C>C <H>H <M>M <L>L (ai:<ai_total>)

Track | Adjusted % | Band
AppSec   | XX.X | <band>
AI       | XX.X | <band>

Failing hard gates (if any):
 - <gate_name>: <reason>

Floor-breached categories:
 - <track>/<category>: score <raw> < floor <floor_score>

Step 5: Generate the remediation roadmap

This is the core value-add of this skill. Convert the audit JSON into an actionable, prioritized roadmap.

Ranking rules (apply in order):

1. Critical > High > Medium > Low severity, always.
2. Within severity, rank by category.gap_score (the engine already computed this — it's (5 - score) × weight, so it captures both how far a category is from the target and how much it contributes to the overall score).
3. Prefer AI-track categories when the policy pack weights AI ≥ 50% (e.g. cw-internal).
4. Hard-gate failures are P0 — they flip strict_ok and are table stakes.
5. Floor-breached categories are P1 — they don't fail strict alone but signal structural weakness.

Read each finding from audit-evidence.json → findings_resolved and ai_findings_resolved. For each top finding, include:

• Finding ID, rule ID, severity, file, line, title
• Which category it rolls up to
• Which compliance control (if pack has a frame) it maps to
• A concrete fix recipe — use the rule_id to determine fix type:
  • OS-SECRET-* → move to env var / secret manager, rotate the credential
  • OS-CODE-001 (eval/Function) → replace with safe parser / static dispatch
  • OS-AUTH-* → add auth middleware to the route
  • OS-AI-PI-* → isolate untrusted input (delimiter, separate template role, structured output enforcement)
  • OS-AI-TOOL-* / OS-AI-AGENT-* → add tool allowlist, require approval for sensitive actions
  • OS-AI-RAG-* → scope retrieval by tenant, cap PII class, disable write connectors
  • OS-DEP-* → bump the vulnerable dependency
  • OS-CONFIG-* → harden Dockerfile/compose/env file

Shape the roadmap as a numbered list with ~3-7 entries per phase, grouped:

• Phase 1 — Strict-gate unblockers (P0): fixes that flip any failing critical/high hard gate to pass.
• Phase 2 — Floor breaches (P1): raise floor-breached categories to their floor.
• Phase 3 — Band lift (P2): next next_gaps items to push the overall score up one band.
• Phase 4 — Hygiene (P3): remaining medium/low findings.

Each roadmap item: [severity] category/rule_id — file:line — one-line fix — est. effort (S/M/L).

Do not invent fixes. If a finding's fix is non-obvious from the rule_id, read the file at the reported line first, then propose a fix anchored in the actual code.

Mode: FIX

If --fix is in arguments:

1. Run assess (Steps 1-5) once to build the roadmap.
2. Enter a bounded loop (default 5 rounds, override via --max-rounds N):
   • Pick the highest-priority roadmap item.
   • Use Edit/Write to apply the fix anchored in the real code at file:line.
   • Re-run openshield audit --mode pr-diff --out .artifacts/security-audit to re-score the delta.
   • If the gap for the chosen category closed, continue to the next item.
   • If the same finding persists after a fix attempt, mark it as "needs human review" and move on — do not burn rounds retrying.
3. Terminate when:
   • overall.strict_ok === true AND band is at least operational, OR
   • max rounds hit, OR
   • no remaining roadmap items match your authority (e.g. requires secret rotation, infra changes).
4. Final report: show before/after overall score + band, which gates flipped, which items shipped, which remain.

Do not:

• Suppress findings to make the score go up. Suppressions are only valid for documented analyzer-on-analyzer false positives with specific reasons and ≤90-day expiry. If in doubt, ask the user.
• Touch files outside the target path.
• Commit or push — the user does that.

Mode: HISTORY

If --history in arguments:

1. Use mcp__omni-mem__search with query security-audit <project> and workspaceId matching the current workspace.
2. If the MCP tool isn't available, fall back to reading .artifacts/security-audit/audit-report.json if present.
3. Present a timeline:

   Security Audit History — <project>
   Date       | Pack        | Overall | Band               | Strict | Next gap
   2026-03-02 | default     | 65.4    | Operational        | FAIL   | appsec/authn-authz
   2026-04-17 | cw-internal | 92.3    | Enterprise-Mature  | ok     | appsec/coverage
   

4. STOP — history mode is read-only.

Policy pack guidance

Pack selection rules when the user doesn't specify:

• Compliance mentioned (SOC 2 / HIPAA / PCI / ISO / NIST / CSF) → pick the matching pack.
• CW engagement (user says "audit this client", "for the report to ") → cw-internal.
• AI-heavy codebase (detected anthropic / openai / MCP) → default with --profile ai-app unless compliance mentioned.
• Otherwise → default.

Suppressions handling

• If the target has openshield-suppressions.json or .openshield-suppressions.json at its root, pass it via --suppressions.
• If the audit produces findings that are clearly analyzer-on-analyzer false positives (the rubric is detecting openshield's own patterns in a project that imports/vendors openshield), propose suppression entries but don't write them without user confirmation — always include reason + expires_at (90 days out).

What this skill does NOT do

• Does not re-invent the rubric. OpenShield owns the engine; this skill is a prompt wrapper.
• Does not edit openshield itself. Bugs in openshield go through the openshield repo.
• Does not decide licensing, governance, or compliance certification. Report is readiness-oriented; legal sign-off is human-only.
• Does not push to remotes or commit.

Memory

After each assess/fix run, save the score + band to omni-mem via mcp__omni-mem__save_memory when the MCP tool is available, so --history can retrieve it later. Include: target path, policy pack id, overall adjusted percent, maturity band, strict_ok, timestamp, top 3 next_gaps.
